Problems solved by technology

These organic solvents are cheap and have a good dissolving effect on pesticides. They have been used as solvents for pesticides for a long time, but these solvents only play a role in dissolving pesticides, and cannot effectively improve or increase the efficacy of pesticides. In addition, in the general trend of green environmental protection Under the current situation, this kind of solvent that pollutes the environment and may cause harm to the personnel in the spraying operation has become increasingly unable to meet the needs of development.

Abstract

The invention relates to the technical field of pesticides, in particular to a preparation method of a soybean oil emulsifier for pesticides, which comprises the following steps: 1, weighing a properamount of soybean oil and emulsifier, mixing the raw materials in a reaction kettle, and uniformly stirring the raw materials; 2, weighing a proper amount of cosolvent and synergist, adding the cosolvent and the synergist into the reaction kettle, stirring all the components at 30-60 DEG C to be fully mixed, and naturally cooling the mixture to obtain a finished product. In the invention, the epoxidized soybean oil is used as a main component, so that the problem that oxidative rancidity is easy to occur when pure natural vegetable oil is directly used is avoided, dissolution of pesticides isfacilitated, and harm of organic solvents such as benzene to the environment and operators can be prevented; by using the cosolvent, the synergist and the like, on one hand, the surface tension of theepoxidized soybean oil solvent can be reduced, the solubilizing effect on the pesticide is achieved, and on the other hand, the emulsifying effect of the emulsifier after being dissolved in water canbe enhanced. Meanwhile, the preparation method is simple, the number of operation steps is small, and the prepared finished product is environmentally friendly, good in stability, lasting in pesticide effect and little in environmental pollution.

Description

Technical field [0001] The invention relates to the technical field of pesticides, in particular to a method for preparing a soybean oil emulsifier for pesticides. Background technique [0002] At present, pesticide formulations mainly include emulsifiable concentrates, water emulsions, microemulsions and soluble liquids. Emulsifiers have always been favored by farmers because of their good dispersion effect during use, high effective drug concentration, and simple preparation during use. A large amount of organic solvents such as toluene and xylene are used in the process. These organic solvents are cheap and have good dissolving effect on pesticides. They have been used as solvents for pesticides for a long time. However, these solvents only play a role in dissolving pesticides, and cannot effectively improve or increase the efficacy. In addition, they are in the trend of green environmental protection. Under the circumstances, this kind of solvent that pollutes the environmen...
